I would use "in" in all of these.
Student or Learner
I've seen this topic covered before but I'm still struggling to get my head around using 'training on', and 'training in'.
I'm writing bullet points for staff appraisals and I'm noting where further training is needed. For example:
Training in cross infection control policies
Training in booking an appointment
Training in reception procedures
I cannot seem to figure out whether I should write 'in' or 'on'. I know it sounds silly to be worrying over it, but I'd like to know both for now and for future reference.
I'd use "in".
Many thanks. I'd actually first written 'on', which then got me thinking. In what instance would I use 'on', just for future reference?
